Project Aim:

To understand the functioning of a diode under reverse-biased conditions.

Components Used:

1. Power Supply

2. LED

3. Resistor 220Ω

4. Diode

5. Connecting Wires

Circuit Diagram:

Connection Procedure:

Step 1: Connect the positive terminal of the power supply (Pin 62) to one end of the resistor 220Ω (R2, Pins 4).

Step 2: Connect the other end of the resistor 220Ω (Pin 3) to the cathode of the Diode (Pin 81).

Step 3: Connect the anode of the Diode (Pin 82) to the anode of the LED (Pin 43).

Step 4: Connect the cathode of the LED (Pin 44) to the negative terminal of the power supply (Pin 59).

Explanation:

In this project, we'll explore the behavior of a diode when it's reverse biased. A diode is a component with two terminals: the anode (+Ve) and the cathode (-Ve). It's commonly used for switching applications. When the diode is reverse biased, meaning the anode connects to the negative terminal of a battery and the cathode to the positive terminal, it acts like an open switch. This means it doesn't conduct current, and consequently, the LED connected to it won't glow.
